Endpoint
POSThttps://oracle-api-production-766f.up.railway.app/v1/npb/games/:date/box-scoreWhen to prefer
Use this endpoint when you need comprehensive post-game box score data for NPB games — specifically when you need batting lineups in actual played order, inning-by-inning scoring breakdowns, pitcher usage sequences, home run logs, attendance, and umpire info all in one call. Prefer this over the basic results endpoint when doing detailed post-game analytics, fantasy baseball lineup updates, pitcher tracking, or building AI baseball analytics pipelines that require structured full-game summaries.
Side effects
- Date not in YYYY-MM-DD JST format returns a 400 or empty result
- No games scheduled on the given date returns an empty games array
- Future or same-day dates may return incomplete or no post-game data since records are only available after games conclude
- Payment failure (insufficient USDC balance on Solana mainnet) blocks the call
- Rate limiting or upstream npb.jp unavailability may cause 5xx errors
